SPECIFICATION forming part of Letters Patent N0. 676,382, dated June 1 1, 1901. Application tiled January 14, 1901. Serial No. 43,176. (No model.)

To` otZZ whom it may concern.-

Be it known that I, CLARENCE R. BUMBAR- GER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Shutter Workers, of which the following is a specification.

The invention relates to an improved shutter-worker, which may be operated from inside or outside of a building for opening and closing a pair of or a series of shutters simultaneously, as well as to permit of the opening and closing of the shutters independently of each other. g

The invention further aims to construct an apparatus of the above character which shall be simple in its construction, strong, durable, and efticient in its use, and comparatively inexpensive to manufacture; and to this end the invention consists of a shifting or operating rod brought into engagement with the shutters by a suitable operating mechanism for opening and closing the same, and, further, in

'providing said shifting or operating rod with means for disengaging the same from the shutters to. enable the latter to be closed and opened independently of each other.

The invention finally consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings,

forming a part of this specification, `wherein like reference-numerals indicate corresponding parts throughout vthe several views, and in which- Figure lis a side elevation of my improved apparatus for working shutters. Fig. 2 is a detail view of the bracket carrying the rotating screw. Fig. 3 is a like View of the carrier. Fig. 4L is a similar view of the shutterstop. Fig. 5 is a like View of the shutterguide. Fig. 6 is a like view of the shutterretaining strip for the shutters. Fig. 7 is a like View of the catch or dog carried by the shifting or operating rod.

Referring to the drawings by reference-nu- Vclination.

and may be of any desired length. The hangers 3 are of the ordinary construction, provided with the usual roller, (not shown,) which operates upon the track in the wellknown manner.

Secured to the outside of the building and A.

to each of the window-frames is a shutterstop for limiting the movement of the shutters in one direction, and which consists of an elongated bar 4, having the end 5 secured to the window-frame and the opposite end 5 carrying a stop-clasp 6. The latter, with the end 5', is secured to the building and arrests the movement of the shutter.

The reference-numeral 8 denotes the shutter-guide, which is attached to the building below each of the windows and is constructed in such a manner as to allowV the shutter to play loosely between the wall of the building and the roller 9, carried by the guide 8. The latter is provided with a curved stop-arm 10, so as to catch the shutter if it should be drawn too far to the right. p The shutter has secured to near its lowerend a retaining-strip 11, having a portion of its length formed at an in- This strip is adapted to be en= gaged by the roller 9 as the shutter closes, which throws the same tight against the wall when the shutter is finally closed.

Connected to the wall of the building at one side of one of the shutters is a bracket 12, in which is pivotally mounted vided with the arms 14C, projecting at right angles to the axis of the spool. The latter is formedv with a square opening extending lengthwiseof the same. Each of the arms 14 has connected thereto au operating rope, chain, or cable'l, the functionof which will be hereinafter described.

The reference-numeral 16 denotes the shifting or operating rod, which extends through the square opening of the spool 13 and'l carries the dog or catch 17, adjustably secured thereto by means of the set-screw 18; The

the spool 131, pro- IOO length of the shifting or operating rod 16 is governed according to the number of shutters in longitudinal alinement.

Secured near the top of each of the shutters is a carrier 19, provided on one face with a bracket 20, Within which is mounted the antifriction-roller 21, suitably connected thereto and to the carrier 19, the roller 21 being adapted to support the shifting or operating rod 16. The carrier 19 is substantially U --shaped, and

the leg opposite the roller 21 is bent to form a projection 22, which extends at right angles to the shutter and is beveled, so as to throwr the catch or dog 17 out and turn the shifting rod, as will be hereinafter described. Connected to each end of the shifting or operating rod 16 is a rope, chain, or cable 23, Winding upon a Windlass arranged at the outside ot the building. The windlass consists of a suitable frame 24, connected to the outside of the building and in which is journaled a sprocket-Wheel, chain-Wheel, or drum rotated by a'crank or handle 26 and over which runs the rope, chain, or cable 23.

The reference-numeral 27 denotes a sheave- Wheel, also mounted in the frame 24, adapted to hold the chain, rope, or cable more closely to the drum or Wheel. The crank or handle 26 may be located at the outside or inside of the building.

Upon the axis of the drum or Wheel is loosely mounted a shifting lever 28, provided with a handle 28, to which are connected the ropes, chains, or cables 15, attached to the arms 14 for operating the same. By moving the lever 28 in either direction a corresponding movement Will be given the arms 14, causing the -partial rotation of the spool 13, thus turning the rod 16, so as to throw the catch or dog 17 into or out of engagement with the projection 2 and the carrier 19.

, The side of the building has connected thereto by means of the brackets 29 a series of pulleys 30, over which passes the rope, chain, or cable 23.

The operation of the device is as follows:

The shutters being closed, as shown in the drawings, the Windlass is operated to Wind the chain, rope,- or cable 23. This causes the shifting of the rod 16 and brings the catch or dog 17 into engagement with the projection of the carrier and carries the shutters therewith, opening the same. This movement is continued until the shutters are arrested at they end of the track 2. By reversing the movement of the Windlass the rod 16 will travel in an opposite direction, the catch engaging the carrier and closing the shutters, themovement in this direction being arrested by the stop-clasp 6. W'hen the shutters are all open and lit is desired to close one independently of the others, the lever 28 is moved toa reverse position, and a corresponding movement is given the arms 14 by means ot' thecables 15, causing the turning of the rod 16 and elevating the dog or catch 17 to prevent the engaging of the latter with the projection.

This will permit the shutters to be closed independently. shutters independently of each other, the rod 16 is rotated and drawn back bythe Windlass the length of a shutter. The shutters are then free to move, as the catch or dog will notengage the carrier. Y

It is thought the many advantages of my improved apparatus Jfor opening and closing the shutters of buildings can be readily understood from the foregoing description,taken in connection With the accompanying drawings, and it will be noted that various changes may be made in the details of construction Without departing from the general spirit of my invention.
